DOUBLE-ACTING PUMP.

SPEOIFIdATION forming part of Letters Patent No. 250,106, dated'November 29, 1881.

' Application filetLJuly 13,1881. (No model.)

To all whom it may concern:

Be it known that I, HENRY SANTROCK, a citizen of the United States, residing at Cedarville, in the county of Smith and State of Kansas,,have invented certain new and useful I mprovements in Double-Acting Pumps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a sectional elevation of my invention. Fig. 2 is a perspective view of that portion of the pump located above the curb or platform. Fig.3 is a detail view, in section, of one of the pumptubes carryingthecheck-valve, and showing the manner of connecting thereto the detachable wiregauze tube.

The present invention has relation to certain new and useful improvements in doubleacting pumps; and it consists in the details of construction substantially as shown in the drawings and hereinafter described.

In the accompanying drawings,Arepresents the pump-cylinder, centrally located between the tubes B (1, said tubes connecting with a dischargetube, D, extending above the curb or platform a and provided with the usual discharge-spout, b.

The tube D is firmly connected to the platform a by braces c, bolted thereto and to the tube, as shown in Fig. 1.

The piston d is provided with the usual solid head, the rod thereof extending through and above the upper end of the tube D, and has pivoted to it the usual pump handle, E, said handle being pivoted to a fulcrum -Iever, e, which, in turn, is pivoted to a short horizontal arm,f, projecting from the tube D. The extremeupper end of the piston-rod passes up through a guide-arbor, F, cast with the tube D, which steadies the rod in its vertical movement.

The arbor F has an elongated opening, 9, through which passes the end of the pumphandle E,so as to prevent undue lateral strain upon the handle when pumping.

The pump-cylinder A is provided with discharge-openings h 2', the former communicating with the tube 0 between two check-valves,

k l. and the latter opening, '6, communicating with the tube B between similar valves, m a,

the latter valve being located in the end of a removable U-shaped tube, G.

The cylinder A, at its lower end, is closed by a screw-cap, 0, so that access may be had to theinterior of the cylinder when found necessary for repairing or for other purposes.

The essential feature of my invention is the wire gauze pipe H, which has connected at each end a metal band, 19, to admit of its being removably connected to the ends of the tubes 0 G by suitable screw-bolts or other convenient means. Any means, however, may be employed for connecting the pipe H to the ends of the tubes so long as it will admit of its being removed for cleaning or repairing or for substituting a new pipe, as may be required.

Heretofore the valve-openings or openings in the pump cylinder or tubes only were covered with wire-gauze. This, however, would soon clog up from the foreign matter in the well, and would to an extent impair the operation of the pump. This evil I entirely remove by the employment of the wire gauze cylinder or pipe H, which presents a large filtering-surface to the water before it enters the valve openings, the extent of surface presented by the pipe H rendering it almost impossible for it to become clogged to such an extent as to obstruct the flow of water through the meshes of the gauze cylinder or pipe.

The general construction of the pump and the location of the valves above and below the openings h irender the operation of the pump both simple and effective.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a double acting pump, the cylinder A, with piston d, and tubes '13 G D G, arranged as shown, in combination with the check-valves 70 I, located above and below the opening h, and valves m a above and below the opening z, said tubes 0 G having detachably connected thereto a wire-gauze pipe, H, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

HENRY SANTROOK.
